Hello,

Let's say that I buy a 150A three phase meter. After some time, I need to measure currents above 150A and I would need the 250A version. Could I simply buy three 250A current clamps and connect them to the meter? In case, what are the requirements for the clamps?

Thanks

Alex

Hi, the energy meter is calibrated with CT independently.
So, the 150A and 250A CT is not exchangeable. otherwise, it will affect the reading accuracy.

This is why we do not have CT in sold.
